Redmond O'Hanlon describes his extraordinary three-week trip on an Orkney trawler as it journeys far into the north Atlantic in search of its catch. Young skipper Jason Schofield has a 2 million pound overdraft on his boat, the Norlantean, which is why he has to go out in a Category One Force 12 hurricane when the rest of the Scottish fleet has run for shelter. O'Hanlon may not be much help when it comes to seamanship - in the words of one of the crew, he doesn't know his arse from his tit - but he is able to wax lyrical on the amazing deep-sea fish to be found north of the Wyville Thomson Ridge: greater argentine, flying squid, blue ling, the truly disgusting hagfish and many other exotics.

Combining humour with erudition, O'Hanlon has written a vivid and compulsively readable account of a journey that for sheer terror beats all his previous adventures.
